Abstract: 1,229,794. Image reproduction. CROSFIELD ELECTRONICS Ltd. 18 June, 1968 [20 June, 1967], No. 28342/67. Heading H4F. A half-tone reproduction of an image, e.g. on a transparency, is made by exposing a lightsensitive layer on which the reproduction is to be obtained to a light source without the intervention of a screen, wherein the light source is controlled jointly by image signals obtained by scanning the image to be reproduced and by screen signals obtained by scanning light through a half-tone screen on to a photo-electric element. The apparatus shown includes transparency analysing and screen analysing drums 2, 30 on which the transparency and half-tone screen are respectively positioned and scanned synchronously by light from lamps 12, 31 by the combined actions of the drum rotation and the transverse scanning of analysing heads 16, 32 which are mechanically linked to prisms 10 within the respective drums. A comparator 34 combines the image and screen signals and compares them with a fixed reference level. Whenever the combined signal is above this level, which will occur during a period of each cycle of the screen signal dependent in length upon the amplitude of the image signal, an exposing head 23 is energized, thereby exposing a dot of corresponding area on the light-sensitive emulsion which is mounted on an exposing drum 4 and is scanned synchronously with the transparency and the half-tone screen. A half-tone reproduction of the transparency is thus obtained. The three drums 2, 4, 30 may be replaced by different areas of a single drum. The density as well as the area of each dot of the reproduction may be made dependent upon the image intensity by supplying the output from the comparator (62), Fig. 5 (not shown), to a switch (64) which feeds to the exposing scanner (23) either a fixed signal or the image signal. The switch operates so as to pass the latter signal when the combined image and screen signals exceed the reference level of the comparator. In another apparatus, Fig. 2 (not shown), the optical screen scanner of Fig. 1 is replaced by a C.R.T. (44) whose scanning characteristics are controlled in synchronism with the scanning of the transparency. The flying spot of the C.R.T. in turn scans a half-tone screen and the resultant screen signal is amplified and applied to a comparator as in the first embodiment. In this case the screen scanned may correspond to only a portion of the total image area, and may in fact contain only a single dot. It is also possible to store the screen signal in a magnetic core or tape memory or in an electronic shift register, and to read it out as required in synchronism with the scanning of the transparency and lightsensitive emulsion.

Abstract: 1,231,102. Optical direction finding. NORD-AVIATION SOC. NATIONALE DE CONSTRUCTIIONS AERONAUTIQUES. 16 April, 1968 [17 April, 1967], No. 18008/68. Heading H4D. The Specification describes an optical arrangement for determining the direction of an optical sighting instrument with respect to two sighted objects whereby both the optical direction and the attitude of the instrument can be determined. The optical directions and attitude of a space satellite can be so determined from imaging stars. Thus optical means forms the images of star field H, containing stars E 1  and E 2  in two regions H 1 , H 2 , Fig. 2, subtending 90 degrees with the centre point a (point of passage of instrument axis Z-Z through focal plane). The fields H 1  and H 2  are scanned by a spiral system of slots j in a rotating disc G 1 , Fig. 5, the slots j having radii (R-n) . . . (R-2), (R-1), Ro, (R+1), (R+2) ... (R+n) and their angular positions in the disc G 1  being marked by respective magnetic signs, (C-n) . . . (C-2), (C-1), Co, (C+1 ) (C+1 ) . . . (C+n), reference sign Co being larger than the rest and the signs being detected by magnetic heads T 1 , T 2 , respectively arranged opposite regions H 1  and H 2 . Photodetectors DH 1  and DH 2  detect the scanned star images. Disc G<SP>11</SP> which rotates with disc G<SP>1</SP> and carries the magnetic signs C also carries angle defining signs I at angular spacings of 2<SP>11</SP> which are detected by magnetic head T 3 . To measure the co-ordinate positions x 1 , y 1  of star image E 2  a counter B 1 , Fig. 8, receiving the outputs of detector DH 1 , head T 1  and head T 2 , counts the number of I pulses occurring between the detected E 2  pulse and the next C pulse, in this case the (C-2) pulse. This count defines angle -α 2 , Fig. 2. Counter B 1  then determines the lateral offset L 2  of the image E 2  from the Y axis, from the relation L 2  = (R-2) tan (-α 2 ). L 2  is then sent to a summing device D and also to a second counter B 2 . The value L 2  tells counter B 2  that, in field H 2 , the image E 2  will be scanned by that slot having a radial extent including (Ro-L 2 ) in this case slot jo. Counter B 2  thus counts the I pulses occurring being the Co pulse and the detected E 2  pulse. This gives angle + α<SP>11</SP> which in turn gives offset L 4 . Offset L 4  is sent to device D which determines the x and y co-ordinates of Eg from the relation x 1  Ro + L 2 , Y 1  = Ro + L 4 . The co-ordinates x 2 , Y 2  of image E 1  are similarly detected and the attitude of the instrument determined therefrom. The images E 1  and E 2  may be differentiated from other star images by their magnitudes Fig. 6 (not shown).

Abstract: 1,231,581. Turbines and wind motors. G.B. BATHURST. April 26, 1968 [Jan.26, 1967], No.3954/67. Heading F1T. A rotor operated by fluid flowing therepast comprises a shaft 2 carrying at least two rigid spars 7 each supporting a blade 1 towards the leading edge of the latter, the blade being of flexible material. When there is no flow therepast each blade 1 is flat or of aerofoil section and may have substantially zero angle of pitch relative to the plane of rotation of the rotor. As the flow increases each blade 1 flexes such that the pitch angle increases and an increasing concavity 3 is formed on the downstream surface 4 of the blade. Vortices 5 formed within the concavity 3 generate suction forces which attract the adjacent flow 6 tending to promote more nearly laminar flow and increasing efficiency. When used in a windmill the power output of such a rotor varies substantially directly with the windspeed. The rotor may be used in a vertical windmill, Figs.4, 5 (not shown) and also described in Specification 1, 231, 582. It can also be used to derive power from tidal or wave motions in water.

Abstract: 1,250,452. Multiplex signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 30 Dec., 1968 [26 Sept., 1967], No. 43692/67. Heading H4R.  In a multi-channel frequency division multiplex transmission system a circuit is switched between a full circuit bandwidth channel when the channel is active and a reduced bandwidth channel when the channel is idle. As described two terminal stations 5 and 6 are interconnected via a cable 9 carrying an equal number of 3 kHz wide channels and 1 kHz wide channels in each direction. Subscribers T 1  and T 2  are connected to the terminal station via switching devices operated by a speech detector so that while a subscriber is active, i.e. talking, he is connected to a 3 kHz channel and while he is idle, i.e. listening to the other party to the conversation, he will be connected to a 1 kHz channel. Operation of the speech detector causes the transmission of a control signal to indicate to which channel the other party to the conversation is to be connected to receive the signals.

Abstract: 1,251,866. De-magnetizing cathode-ray tube apparatus. RCA CORPORATION. 7 March, 1969 [11 March, 1968], No. 12151/69. Heading H4T. In an arrangement for degaussing television apparatus, specifically the shadow-mask tube of a colour television receiver, the receiver employing a cascaded voltage doubler type of rectifier circuit for producing the normal D.C. operating voltages, the capacitor portion of the first stage is formed as two parallel paths comprising capacitors 31, 41 (Fig. 1) each in series with a thermistor 33, 43 one of which, specifically 43, is shunted by the series arrangement of a voltage dependent resistor (VDR) 51 and a de-gaussing coil 53. The operation is as follows. On switching-on, initially, A.C., one pole of which is grounded, is supplied via switch 13 to, inter-alia, the rectifier circuit and due to the high resistance of the thermistors when cold the major part of the charging current flows in the shunt path including the coil 53. As the thermistors heat up the falling resistance results in a reduction of the current flow in the coil 53 and a reduction in the voltage applied to the VDR 51 so that the resistance of the latter increases. The A.C. flowing in coil 53 is thus gradually reduced to zero to effect the required de-gaussing at which point the resistance of the series arrangement of the coil 53 and the VDR 51 has a high value so that negligible current flows therethrough and the charging current now flows through thermistor 43 (and through thermistor 33 which now has a low resistance). By dividing the capacitor portion of the first stage of the rectifier into two parallel paths the capacitor operative in the de-gaussing circuit, capacitor 41, may be given a capacitance value of the same order as that of the second stage capacitor 73 so that current pulses of the same magnitude flow during each half-cycle of the A.C. input. This arrangement avoids undesirable spot shift effects which the use of an asymmetrical charging current would give rise to whilst allowing the use of capacitance values resulting in maximum efficiency and economy in the design of the voltage doubler rectifier circuit. The two thermistors should be in close thermal contact and may be replaced by a three-terminal device containing two thermistors (Fig. 2, not shown).  The filament transformer 15, which has a tap TH for use under condition of high line voltage so that correct filament voltages are available, supplies the filament of the picture tube 19 via the secondary winding TS and filaments of the damper tube in the horizontal deflection circuit and the series string connected filaments of the remaining tubes via taps, DF and FS respectively.
